He was found at 22 Wadsworth St. after Boston police received a call about an unconscious man at 11:58 p.m., said Officer James Kenneally, Boston police spokesman.

Barksdale was taken to St. Elizabeth’s Medical Center in Brighton, where he was pronounced dead three hours later, according to a statement on BU Today, a university website.

The cause of death was not released, but campus police said there was no indication of foul play, according to the website. Boston police said in a statement that “no visible injuries or trauma were observed on the victim.’’

“We’re just heartbroken,” BU spokesman Colin Riley said in a phone interview.

Riley was unable to say who lived at the Wadsworth Street address or why Barksdale was there. Barksdale was a resident of the Towers dormitory at 140 Bay State Rd. and a member of the Sigma Alpha Mu fraternity, according to BU.

At the Towers Saturday night, students remembered Barksdale as a warm and affectionate young man with an ever-present sense of humor.

“He was always a great guy,” said Christian Walls, 19. “He liked telling jokes, pranking people ... It’s a loss for tons of people that knew Tony, and he’ll be sorely missed.”

Lauren Tzirides, 19, said she often hung out on the third floor where Barksdale lived.

“I remember he would always give me the biggest bear hugs,” she said.

Ben Sabath, also 19, said Barksdale’s death was sudden and surprising.

Sabath said Barksdale and some friends had recently talked about a project to create a device capable of making microwaveable toast.

“He was always there to make people happy,” Sabath said.

The apartment where Barksdale was found is in a row of six weathered two-story stucco townhouses at the end of Wadsworth Street.

Tanya Washburn, 41, who lives next door to the apartment, said she does not know much about her neighbors in the apartment where Barksdale was found, but they appear to be college-aged men. She has asked them to turn down music a few times and they have always cooperated, she said.

Washburn said she thought they had a party Friday night, but it wasn’t particularly loud. She said they did not throw parties frequently.

Saturday evening, Boston police officer Chris Long stood sentry outside the front door to the darkened residence. Long said he and his partner were guarding the front and rear entrances. “No one in, and no one out,” Long said he was told by his supervisor.

He said when his shift began at 4 p.m., the apartment was empty, but he couldn’t say if the residents had been asked to leave by police or chose to stay away.

“Whenever there is a death of one of our own it affects all of us,” Dean of Students Kenneth Elmore said on BU Today. “Our entire community is deeply saddened. I hope that students will look out for each other. I hope they will use the resources that are available here, and I hope they reach out to friends, parents, and loved ones.”

Counselors were made available at the Franklin Lounge in the Towers Saturday evening.
